Ticket #15535, comment 8
initial v1 1 1 I ran into this issue on Sage 6.4.1 trying to compute characteristic polynomials. I was computing the characteristic polynomial of hundreds of thousands of 3x3, 4x4, ..., 8x8 integer matrices, and at some point I got the following: 2 2 3 {{{ 3 4 sage: A = matrix(ZZ, 4, 4, [50528, 38927, 19455, 31617, 58686, 39770, 31059, 21905, 13382, 35615, 18158, 11629, 25923, 12324, 51823, 27000]) 4 5 sage: A.charpoly() … … 7 8 sage: B = copy(A); B.charpoly() 8 9 x^4  135456*x^3 + 1234244249*x^2 + 17242461420805*x  995535814473032365 10 }}}
